Figure 2 is a front elevational view of the open- 20 er.

Figure 3 is a top plan view of the structure shown in Figure 1.

Figure 4 is a rear elevational view fragmentarily showing the opener. 5 Figure 5 is a perspective view of the base plate.

Figure 6 is a side elevational view of the perforating lever.

Referring to the drawings wherein like numerals designate like parts, it can be seen that 30 the opener consists of the base plate 5 having the upstanding wall 6 laterally from which extends the guides l8, vertically spaced and through which the slide bar 9 is disposed. The guide 8 is wider than the guide I, the slide bar 9 being 35 snugly disposed through the guide 1 and loosely disposed through the guide 8. the wall 6 into the guide 8 is the boss In for engagement into any one of the openings I l on the adjacent side of the bar 9. A strip spring I2 is 10 disposed from the guide 1 at the inner side there- Extending from of, downwardly and through the guide 8 and formed in such a manner as to exert tension on the bar 9 in the direction of the boss 10. As can be seen in Figure 2, the openings represent a multiplicity of circular recesses merging together 5 into a single elongated slot.

The lower end of the bar 9 is provided with a pair of ears l3 for preventing displacement of the bar 9 from the guides 1-8.
